Mr. Jarvis and his assistant Joe? went into field with me. Looked over lower section on West flank of WCHs. Mr. Jarvis spotted a fault? in west end of WCHs better check it because it looks as if #4 in drop to Uddenites Saddle. {note: illustration: bed 1: covered bed 2: 7/2/57/2; 27' bed 3: 3'; 7/2/57/1 bed 4: 11'; Uddenities zone bed 5: 5'; King's gray #2 limestone bed 6: 1.5' bed 7: 2' bed 8: 1.5'} PG. 40 CR's Section 20 (GSA M.88) Section V West end of the WCHs proper - measured N20W from outlier [about 300 yards west of King's Sec 24]. Below covered by out wash - Uddenites zone probably. 1) Limestone conglomerate, with crinoid and brach frags., conglomerate cobbles 1' to 4" diameter. 16', gray outcrop - top surface is near flat, has an inch zone weathered brown. Many of the crinoid stems are relatively unbroken and probably have not had a great deal of erosional transport. 2) Covered, 25' - seems to be an interval of gray shale and brown weathering calcarenite. 3) Calcarenite - Brown weathering, lower surfaces appears to be a disgested ss [burrowed]. The upper surfaces are finely laminated - 4-6" beds of ss with interbedded silts and clays, 5'. 4) Shale, blue-gray in part covered 12'. 5) Limestone, similar to #1 below, pebbles are 1/2" in diameter however; Near top is a good fusuline zone - this horizon divides vertically to the west - the upper part forming King's bed "4", 16'. PG. 41 {note: illustration: bed 1: 16'; 7/3/57/1 bed 2: 25' bed 3: 5' bed 4: 12' bed 5: 16'; 7/3/57/2; Top of King's #2 (gray) limestone(?) bed 6: 163'} 6) Covered 163' - How many beds are covered here is only guesswork - The value of this interval is of comparative proposes only. 7) Limestone, massive gray weathering, a shell hash which shows very little transportation. Coral, (long slender tetracorals), bryozoans, isolated fusulines, brachiopods, crinoid stems. lower 18' massive - upper 5' in 6" to 1' beds. 7/3/57/3 total 23'.
